Numerous scientific experiments with humates obtained naturally biologically without the use of any chemical additives (such humates include coprolites-humates formed as a result of the vital activity of worms and humates obtained through the microbiological vital activity of special microbes) have shown that they can not only dramatically increase the yield of any crop, but also to restore lifeless lands, to reclaim areas polluted with oil products, heavy and radioactive metals and also saline soils.
Our company offers a method of producing humates by processing fresh chicken manure by certain strains of mutagenic microbes grown in reactors of BGU VRS type under anaerobic conditions.
They have been found to be effective in reclaiming saline or oil-contaminated soils.
Saline soils are those that have high levels of soluble salts, while oil-contaminated soils have been polluted with petroleum hydrocarbons.
When biogumates are applied to saline soils, they can help to reduce the levels of soluble salts. This is because biogumates can bind to the salts and prevent them from leaching into the soil. As a result, the soil becomes less saline and more suitable for plant growth.
In oil-contaminated soils, biogumates can help to break down the petroleum hydrocarbons. Biogumates contain natural enzymes that can degrade the hydrocarbons, making them less toxic to plants and other organisms in the soil. In addition, biogumates can also help to bind to the hydrocarbons, preventing them from leaching into the groundwater.
Overall, the use of biogumates for reclaiming saline or oil-contaminated soils is a promising approach that is both environmentally friendly and cost-effective. By reducing the levels of salts and petroleum hydrocarbons in the soil, biogumates can help to restore the health and productivity of these damaged soils.
Application of humates on soils polluted with oil product
Heavy petroleum products (used oil in a dose of 3 l/m2) were covered with sand mixed with different doses of Solid Biohumus Fertilizers (hereinafter referred to as humates) per 1 ha (0, 30, 60 and 90 t/ha).
Then, "Chepelev's Memory" sort of barley was sown. Each plot received 500 seeds of "Chepelev's Memory" sort of barley.
Barley sprouting was observed as the root system developed and reached the saline horizon; the plants in the control variant began to die off and survived only at the periphery of the plot. This was not observed in plots with humates, which was reflected in barley yield. Barley grew better on the plots with the maximum humates application.
Application of humates had a positive effect on barley yields. Barley also grew better on plots with maximum application of biofertilizer.
Barley yield on soils, which were artificially polluted with oil products
Barley yield on soils, which were artificially polluted with oil products
A graph shows the yield of barley grown on soils that were artificially made polluted with oil products. Different amounts of solid biohumus fertilizer (SBR), also known as humates, were added to the soil in doses of 0, 30, 60, and 90 tons per hectare. The yield of barley was measured and is shown in the graph.
A diagram shows Number of plants and weight of grains per a plot on soils that were artificially made polluted with oil products. Different amounts of solid biohumus fertilizer (SBR), also known as humates, were added to the soil in doses of 0, 30, 60, and 90 tons per hectare.
Thus, application of biofertilizer on soils contaminated with oil products weakens the toxic effect of oil products and increases barley yield from 0.50 (control) to 1.29 (60 t/ha TBU) and to 2.67 t/ha (90 t/ha TBU) with increasing the dose consistently.

The graph depicts the humus concentration in soils that were made polluted with oil products. The experiment involved adding different doses of solid biohumus fertilizer (SBR), also known as humates, to the soil in amounts of 0, 30, 60, and 90 tons per hectare.

It follows from the table that the use of humates causes an increase in the content of humus and mobile plant nutrients in the applied soil.
Thus, biofertilizers in doses of 60 and 90 t/ha reduce toxicity of oil-contaminated soils and increase barley yields.
